Ability to Add Tags to a Client Profile when Creating a New Client

When creating a new client (or adding tags to an existing client):

FOR EXAMPLE:
I would like to add a tag for a city/state to all clients I'm working with in a particular state.
I would like to add a tag to a client's profile for all SEO clients vs all social media clients, etc.

This will be quite useful when sorting clients with a search feature based on service category/service provided, or by geographic location.
